In the Sesame Street Pitch Reel, Lesser talks to Kermit about the procedures CTW is taking with their upcoming children's show.

Gerald S. Lesser, Harvard professor emeritus of Educational and Developmental Psychology, served as Chairman of the Children's Television Workshop board of advisors from 1969] through 1996. He played an instrumental role in shaping the Workshop's educational goals for Sesame Street, developing what became known as the CTW Model.

Lesser penned the 1974 book Children and Television: Lessons from Sesame Street, providing an early production history and analysis of the research and pedagogical approaches as well as criticism. Lesser is currently writing a history of CTW's international coproductions.
